Heat and humidity will be on the rise over the next few days, with thunderstorms becoming more likely by the weekend.
High pressure has moved south of the region. The clockwise flow of air around the high pressure will start to import higher humidity, and warmer temperatures, northeast towards the Finger Lakes.
The temperatures themselves will only be a few degrees warmer each day, but the humidity will greatly increase. Temperatures today will be similar to Tuesday, with most places near or just above 80 degrees. However, instead of dew points comfortably in the 40s, they will start to reach into the upper 50s to near 60. This will start to feel a bit muggy for some, but generally isn’t too uncomfortable.
On Thursday, temperatures will start to rise into the low and mid 80s with dew points near or above 60 degrees. Friday will reach into the mid 80s and dewpoints will be well into the 60s. Saturday looks like the hottest day, with highs ranging from the mid 80s to near 90 degrees in a few spots. Dew points will rise to near 70 degrees, which will make it feel close to or above 90 for most of the region.
As far as precipitation goes, the set up for showers and thunderstorms is weak today and Thursday. Generally speaking, it will remain dry both days, though one or two brief pop up showers cannot be totally ruled out, especially on Thursday.
More widespread active weather will start to move in for Friday, with a few morning showers and scattered afternoon thunderstorms. Scattered thunderstorms will also pop up Saturday afternoon within the very hot and humid air. Severe weather is generally not expected, but one or two storms could briefly contain some small hail or gusty winds.
Temperatures will retreat slightly on Sunday and Monday, thanks to an increase in expected cloud cover and more widespread thunderstorms. These storms will be triggered by a west-moving front from New England. The details on how rainy these two days ends up are a bit uncertain, but severe weather again looks limited.
The weather should return to being nearly picture perfect next week, with highs back in the 70s to low 80s and more comfortable humidity levels.
